Jeff England, director of transportation projects for NAC International, pointed to the large stainless steel canister, which looked like a giant-sized silver dumbbell, perched on the flatbed of a semitrailer truck parked in the middle of the expansive exhibit hall in the Phoenix Convention Center.

We hold a 110-gallon drum capacity."
